i use a 20" box fan in a top corner for my exhaust, passive intake through hole near bottom corner of the room with a humidifier near it.. made room 4 x 8 x 7 with black poly and duct tape. the fans rated for 2500cfm on high.. more than enough to cool my 400 and 600 batwings

edit: just have to add a tunnel (iused a cardboard box, it fit perfect) on the exhaust side of fan to block light from going in

thats smart i have like 4 box fans so i could try it out that way i just dont want to be cutting alot of holes in my room just some small ones for some squall fans
i was thanking 2 exit fans and and no intake fans bc like i said my rooms not sealed

one fan for each room when i split it one for flower one for veg

Try hanging a wet towl in front of your fan, and when the heater is on do the same there.

This is the only plant in my room doing this, the strain is Darkstar. I'm guessing the problem is strain specific, and nutrient related. Could this be lockout from too high of a pH. I know it is around 6.7 instead of 6.2. It is only on a few of the middle fan leaves, also. The bottom, and the top fan leaves aren't doing this. Thanks for any help. Second pic is a leaf on the exact same plant, only one node down.

Sorry Bama, your thread got sidetracked there, and nobody even mentioned it.
Are you in soil?
I'm kinda curious, because you mentioned 6.7 and 6.2
If you're in soil, that's not too bad, aim for 6.5, but if you're in coco or something, you're pretty high.

Your leafs are ” curling” or ”hooking”, from to much fert, or over feeding. Its NOT humidity! 20% humidity may stunt growth a bit but will not cause the effect you are experiencing! I run my humidity low also and it keeps my plants free of fungi! I get great results! Check your ppm, and cut back a bit on your feeding Schedule and it will correct itself!
